The observations you collect through Nature's Notebook are being used every day by scientists, resource managers, and more. Read more below about how the timing of leaf color-change is expected to be delayed in the future - this research was made possible by the data you've submitted!

These ground-based observations can be enhanced with data collected by satellites or landscape-scale cameras. You can learn more about how data collected by satellite can be combined with ground-based observations in our Sep 9 webinar, with guest presenter Dr. Andrew Elmore of the University of Maryland Center for Environmental Science. You might also be interested in exploring the link below to phenocams, which collect repeat images of landscapes over many years. Your data are in good company!

Thanks again for all that you do!

What your data are telling us
Your observations suggest that leaf color change will occur later in the year

Princeton-based researchers used observations of leaf color change in common deciduous trees collected via Nature's Notebook to pinpoint the triggers to this event. The results suggest that by the end of the century, leaves may change color weeks later than they presently do, due to increasing temperatures.

What's new at Nature's Notebook and USA-NPN
What do I do if my plant dies? 

It happens... the plant that you're happily tracking through
Nature's Notebook dies. Now what? You can report the plant as "dead" in your Observation Deck. Navigate to "Add or Edit Plants" and select your plant. You'll see "Dead?" as a choice near the bottom of the list of questions about your plant, and if you click that, you can enter details as to when and how it died.

Consider selecting a new plant so you can keep on observing!
Next webinar: Linking Nature's Notebook observations to satellite images

You're probably aware that satellite images provide critical information about our planet, which can be compared to observations taken on the ground. Would you like to know more?

Dr. Andrew Elmore of the University of Maryland Center for Environmental Science will demonstrate the value of satellite images for answering pressing environmental science questions. He will also explain how observations from PopClock participants are being combined with satellite images to better predict the phenology of two important poplar trees. If you aren't already tracking a poplar tree or stand as a part of the PopClock project, you will learn how you can contribute to this research effort.

Recent happenings in the field of phenology
What are 

The phenology observations that you collect and share through
Nature's Notebook are vitally important for supporting scientific discovery, informing human health decisions and resource management, and much more. But can we collect even more data using automated cameras?

Researchers at several institutions, including Harvard University and University of New Hampshire, have deployed "phenocams," or cameras that collect daily photographs of the landscape, across the U.S. These photo streams can then be processed to show the clear green-up and green-down that occurs over the course of the season.
More ways to get involved
How is phenology information useful to YOU?

Have you noticed anything unexpected while making phenology observations in Nature's Notebook? Have you been surprised by your discoveries? Have you used this new-found information to guide your activities, such as when to plant, when to weed, when to spread herbicide on unwanted plants? I'd love to hear what you've learned, or if you use phenology information in new ways.
